Go - append to slice in struct

Question

I am trying to implement 2 simple structs as follows:

package main

import (
    \"fmt\"
)

type MyBoxItem struct {
    Name string
}

type MyBox struct {
           


        

Answer 1

package main

import (
        "fmt"
)

type MyBoxItem struct {
        Name string
}

type MyBox struct {
        Items []MyBoxItem
}

func (box *MyBox) AddItem(item MyBoxItem) []MyBoxItem {
        box.Items = append(box.Items, item)
        return box.Items
}

func main() {

        item1 := MyBoxItem{Name: "Test Item 1"}

        items := []MyBoxItem{}
        box := MyBox{items}

        box.AddItem(item1)

        fmt.Println(len(box.Items))
}
